Answer:

t = 7s + 4

Step-by-step explanation:

The goal is to get t alone. So we should move 7s to the other side of the equals to sign. When we move 7s to the other side of the equals to sign the sign changes to -7s. There are no like terms to be collected so the answer should be 7s + 4 for t.

BlackZzzverrR [31]

Answer:

<h2>Total yards of ribbon bought is 6.993yards of ribbon</h2>

Step-by-step explanation:

Total pieces of ribbon James bought for his craft project = 10pieces. If each pieces of ribbon were 2.1feet long, the total number of feet for 10ribbons is expressed as;

$= 10 * 2.1\\= 21feets$

Converting 21 feets to yards;

1 feet = 0.333yard

21feets = x

x = $21feet * 0.333\\= 6.993yards$

Total yards of ribbon bought is 6.993yards of ribbon

Choose the equation of the line that contains the points (1,-1) and (2,2)

natka813 [3]

(1,-1)(2,2)
slope = (2 - (-1) / (2 - 1) = 3/1 = 3

y = mx + b
slope(m) = 3
use either of ur points...(2,2)...x = 2 and y = 2
now we sub and find b, the y int
2 = 3(2) + b
2 = 6 + b
2 - 6 = b
-4 = b

so ur equation is : y = 3x - 4

When viewed from the front, the rope used to tie down a tent forms a pair of supplementary angles with the ground. Find $m\angle

pentagon [3]

Answer:

<ABC = 49°

Step-by-step explanation:

The sum of two supplementary angle is 180. From the diagram, the two angles are 3x+4 and 8x+11. IF this two angles are supplementary then;

3x+4+8x+11 = 180

11x+15= 180

11x = 180-15

11x = 165

x = 165/11

x = 15

From the attached diagram, <ABC = 3x+4

<ABC = 3(15)+4

<ABC = 45+4

<ABC = 49°

Limited mobility may be a disadvantage of buying because the home is?

Serga [27]

Difficult to sell

Explanation

There are many factors that limit the mobility and they are contributed by factors such as disease and accidental factors and there are many persons with disabilities

Many changes must be done with the layout of the home so if a house is designed with limited mobility it is very difficult to sell. Each and every different mobility homes have certain specifications and different accommodations.

The yards must be designed with mobility issues and they must create a stable and a wide pathway and these are much essential for wheel chair access
